• scorch

  9 180 0.0 Python

  Silent CORruption CHecker and filesystem audit tool

The method I use is to run scorch every night to compute hashes for new files and check around 12% of old files for hash errors every night. Even if your backup is the same day as a ransomware attack, you will still catch it if the attack hits enough files for one to get randomly scrubbed. Also scorch is designed around making the hash database small and independent from the rest of the system, so you can automate copying it to a bunch of different places.
